From Data to Decisions: Explainable AI for Soybean Yield Forecasting
This study proposes the XAI-Crop framework to forecast soybean yield in major producing countries (US, Brazil, Argentina) using multi-source data. It compares the inherently interpretable Kolmogorov-Arnold Networks (KAN) with Multilayer Perceptron (MLP) and Random Forest (RF) models. Findings show KAN achieving comparable predictive accuracy and generalization to MLP and RF in small-sample settings, but with superior interpretability. Feature importance analysis reveals significant regional variability in yield-driving factors, with Solar-Induced Chlorophyll Fluorescence (SIF) consistently being a highly sensitive predictor across all regions. The research demonstrates XAI approaches like KAN can bridge the gap between model accuracy and interpretability, facilitating their integration into agricultural decision-support systems and contributing to sustainable agricultural development. While promising, the study notes limitations including variations in spatial data resolution and the relatively short five-year data series.

Examines the role of Explainable AI (XAI) models, particularly Kolmogorov-Arnold Networks (KAN), in providing transparent and intuitive explanations for crop yield predictions, crucial for trust in decision-making.
Superior Interpretability
KAN achieves comparable accuracy with enhanced transparency in yield forecasting, making it ideal for critical agricultural decisions.
| Feature | KAN (Interpretability Insight) | MLP (Permutation Importance) | RF (Permutation Importance) |
|---|---|---|---|
| SIF (Solar-Induced Chlorophyll Fluorescence) | Consistently high sensitivity, intrinsic explanation of its contribution. | Often high, but 'black box' nature obscures detailed relationships. | Consistently ranked high, often concentrated on this feature due to strong correlation. |
| NDWI (Normalized Difference Water Index) | High sensitivity in US, clear functional mapping reveals water stress impact. | Sensitive, but context-dependent influence is opaque without further analysis. | Varies by region, strong impact where water availability is a key factor. |
| Temperature (Mean/Var) | Regional variability, especially pronounced in BR/AR with clear functional forms linking temperature to yield. | Significant, but specific thresholds and interactions with crop growth are hidden. | Important, especially in BR/AR, with concentrated influence on splits due to strong signal. |
| Soil Moisture (Layers) | Regional variability, critical in BR/AR, direct functional contribution to yield explained. | Influential, but the complex interaction with other features is unclear to stakeholders. | Strong predictor in BR/AR, often grouped with other soil factors in decision trees. |
Evaluates and compares the predictive accuracy, generalization capabilities, and robustness of KAN, MLP, and Random Forest models across diverse agricultural regions under varying sample conditions.
| Country/Metric | Random Forest (RF) | Kolmogorov-Arnold Networks (KAN) | Multilayer Perceptron (MLP) |
|---|---|---|---|
| USA (Overall Ranking) | RF > KAN > MLP (Strongest performance on validation and test sets). | Robust, better than MLP, good generalization but slightly lower accuracy than RF. | Noticeable overfitting in some folds, less robust than KAN. |
| Brazil (Overall Ranking) | Lower fitting capability in low-yield regions (scattered predictions). | MLP > RF > KAN (Comparable accuracy to MLP, similar overestimation in high-yield, stable). | MLP > RF > KAN (Achieves highest accuracy, but shows overestimation in high-yield range). |
| Argentina (Overall Ranking) | RF > KAN > MLP (Stronger advantages under small-sample conditions). | RF > KAN > MLP (Generally better fitting performance than MLP, relatively stable). | Poorer fitting performance in specific folds, less stable compared to KAN. |
| Interpretability | Moderate (Through feature importance analysis; multiple trees can be complex). | High (Intrinsic explainability; visual functions for each feature's contribution). | Low ('Black box' nature; requires external tools like SHAP for interpretation). |

Regional Soybean Yield Forecasting Insights
This study applied XAI models to forecast soybean yield in the United States, Brazil, and Argentina, representing over 80% of global production. The models demonstrated high spatial consistency in primary producing regions of the US.
In Brazil, significant discrepancies emerged in northern areas, with KAN predicting generally higher values than statistical results, suggesting potential for refinement. Argentina showed strong consistency in central regions, but this decreased in peripheral areas.
These regional variations underscore the importance of local conditions (environmental, climatic, management) and data resolution challenges in developing universally applicable models.
Outlines how integrating prior agricultural knowledge with XAI can enhance model performance and trustworthiness, paving the way for more robust and sustainable agricultural decision-support systems.
